Could not create table property widget when selecting a device property

[bautisflow]

Describe the bug When selection a device property in the table property widget and not a device pattern, the widget form cannot be saved.

I am also stuck there, cannot get the point with the "property pattern".

I would appreciate to get the full configuration settings of your demo "Tank configuration". That would surely help to understand what is required to get this feature flying. Regards. Laszlo
